Aduaspace: fixing playback in the game engine.

parenthisize macro args to avoid errors

Cleanup: quiet int overflow warnings

Fix VSE showing FPS during scrubbing

Was intended to be disabled in rBa3b86611a8182, but disabled 3D View FPS drawing instead of VSE drawing. Triple checked but 3D View doesn't draw FPS now, so everything seems fine now.

Note: To recreate this you had to play animation once before scrubbing.

Fix VSE not able to playback after scrubbing (and a couple of crashes)

After scrubbing, Blender kept thinking an animation is played (see animation "Play" button), even after mouse release. This resulted in a couple of crashes, e.g. by pressing Alt+a and then Esc.

(Also minor cleanup)

Use Auto-offset for move_detach_links (alt+D) operator too

Correction to previous commit, git messed up icon binaries :/

Note Editor: Auto-offset nodes on insertion

Implements "Auto-offset" (called "insert offset" in code) feature for Node Editor, developed during and after LSOC :)
Idea and sponsoring by Sebastian K�nig, blendFX, Mathias Eimann, Mikavaa, Knick Design

When you drop a node with at least one input and one output socket onto a an existing connection between two nodes, Auto-offset will, depending on the direction setting, automatically and animated move the left or right and all of its following nodes away to make room for the new node.
The direction for offsetting can be toggled while you are moving the node by pressing ?T?.

The auto-offset is enabled by default but can be disabled in the header of the node-editor. The offset margin can be changed in the editing section of the User Preferences.

Thanks a lot to the sponsors, and especially to Sebastian who helped *a lot* with this. That's how users can help developing Blender!

Node Editor: A bunch of new utility functions

Needed for node insert offset (Auto-offset in UI), but kept separate so people notice it without having to check insert offset commit (not for commit ratio of course ;) )

Allow accessing modal keymap strings directly from keymap

Previously you had to pass operator which in some cases might not be available or hard to get.

Fix T45582: Connect vertex hangs

With multiple branches it was possible the search could run for a long time,
especially when there was no possible path to the target.

Now use a heap to keep track of the best path and finish immediately once its reached.

BMesh connect pair, fallback to identity matrix

For overlapping vertices, a matrix for the operation can't be calculated.

Replace checks for tessface w/ polygons

In these cases we're only checking the mesh has faces.

Missed when updating effects to looptri

Remove MFace use w/ cloth

Complete fix for T45618

Two issues here, normal update was not happening due to own sillyness in
viewport refactor, also normal update code still used triangles.
Now reused Campbell's poly normal recalculation code.

Fix T45632: motion blur (2d filter) not working - in OSX at least

This regression was introduced in Blende 2.73a when we went through a
ghost context refactoring :(
